Original Redmine Issue: 14929
Affected QGIS version: 2.14.3

Hi,

When i try to use processing in batch mode with QGIS clip function.
It's not working error message said :

"unsupported geometry type"

It's from IGN BdTopo and it's polygon with M dimension. See detail on [[http://paste.opensuse.org/92344906]]
Doesn’t work in QGIS 2.14.3
But work with QGIS 2.14.2

Though it was due to GDAL : https://trac.osgeo.org/gdal/wiki/rfc61_support_for_measured_geometries
So build back 2.0.2 instead of using lastest 2.1 but problem still the same.

The problem is due to the presence of 2.5D geometries (nothing to do with M), so the title should be changed

In 2.14, the message is generic: https://github.com/qgis/QGIS/blob/release-2_14/python/plugins/processing/algs/qgis/Clip.py#L63 ( Input layer has unsupported geometry type ). In master it has been made more specific : https://github.com/qgis/QGIS/blob/master/python/plugins/processing/algs/qgis/Clip.py#L72 ( Input layer does not support 2.5D type geometry )

Would like to be more precise.
I've tested on 2.10 and its work perfectly without error

After a feedback with René-Luc D'Hont from 3Liz,

It work again by comment line 64 to 66 in /usr/share/qgis/python/plugins/processing/algs/qgis/Clip.py

        #if geomType in GEOM_25D:
        #    raise GeoAlgorithmExecutionException(
        #        self.tr('Input layer has unsupported geometry type {}').format(geomType))

Export is still Geometry: 3D Polygon so why there is a testing condition in the code ?

This restriction has been added in d4e400a

Why this restriction? A problem with some GEOS version ?
